Meteorological determinants of suicide rates: evidence from population-based data.
Article in BMC public health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundSuicide is a serious and growing public health issue with a complex, multifactorial etiology involving psychological, social, and environmental determinants. Increasing evidence suggests that meteorological and climatic factors may influence the risk of suicidal behavior, supporting their inclusion in prevention and intervention research. This study aimed to examine the relationship between weather variables and suicide frequency in selected Polish cities.
methodsData from 2019 on suicides in Katowice, Łódź, Gdańsk, and Białystok were analyzed in relation to daily meteorological data from local stations of the Institute of Meteorology and Water Management, covering all 365 days of the year. Variables included air temperature (minimum, maximum, average), precipitation and its type, sunshine duration, wind speed and gusts, cloud cover, air pressure, and atmospheric phenomena such as snow, sleet, hail, thunderstorms, fog, and haze. Associations were assessed using Spearman’s rank correlation (p < 0.05).
resultsWeak but statistically significant correlations were found between selected meteorological parameters and suicide frequency, varying by city, sex, and age group.
conclusionsThese findings suggest that weather conditions may contribute to suicide risk. Incorporating meteorological factors into suicide-prevention strategies could enhance early intervention efforts, particularly in the context of ongoing climate change.
